    Description

    Version:

    • The momentary clamping pressure is directly readable on the analogue or digital display on the base body.
    • The live centre is supported by a disc spring pack with a spring travel of approx. 3.7 mm analogue and 2.6 mm or 2.8 mm digital.
    • Short sturdy design with active longitudinal axis. Live centre through hardened and finish ground.
    • Maximum accuracy due to precision roller bearings.
    • With push-off thread and push-off nut.
    • With special seal against dirt and coolant ingress, maintenance-free due to lifetime lubrication.

    With extended centre, point angle 60°/40°.

    Description:

    Lathe centres are mainly used on lathes to support long and slim workpieces, since with these workpieces there would otherwise be a risk of the workpiece bending or moving around as a result of the forces generated.
    The lathe centre is secured with a Morse taper. The workpiece is clamped in the chuck and a counterbore is added using a centre drill. After re-clamping, the lathe centre is then inserted.

    Function:

    IP55: Protected against jets of water from all directions and protected against penetration of dust into the inside (protected against dust), also completely protected against touching.

    Application:

    Whenever the clamping force should be kept within certain limits,either to prevent deformation of the component or to ensure secure clamping with sufficient pressure.
    • As a tailstock centre in conjunction with hydro-mechanical face drivers No. 327451327541 because the drive teeth have to dig into the component.
    • For components that expand significantly due to high machining heat.
    • For clamping long slender components to prevent lateral displacement.
    • For clamping heavy components where a controlled clamping force is required.
